What to check before buying

  • Match the data plate against the order: frame size, mounting and rating have to agree.
  • Check the ingress rating against the installation site — outdoors or in dust the demands differ.
  • Hold the mounting form and dimensions against the existing seat before ordering.
  • The pole count sets the speed — when replacing an older unit, compare this first.
  • For used units, ask about winding condition and bearing play.
  • Ask about parts availability for this series — the running costs hang on it.
